Integrated Analysis of Transcriptome and Metabolome to Unveil Impact on Enhancing Grape Aroma Quality with Synthetic Auxin: Spotlight the Mediation of ABA in Crosstalk with Auxin.

NAA application delays grape ripening, increases β-damascenone and TDN, decreases IBMP, and triggers changes in norisoprenoid metabolisms through ABA and auxin signaling pathways. VvABF2 and VvARF10 are potential regulators. Important for improving grape quality.

Genome-wide identification and comprehensive analysis of the phytochrome-interacting factor (PIF) gene family in wheat.

Scientists studied phytochrome-interacting factors in wheat, identifying 18 genes categorized into four groups. Two active genes, TaPIF2-1B and TaPIF4-5B, were found to impact plant development and stress responses, providing insight into PIF-mediated stress responses in wheat.
